3RU Chassis Description
The Model 3020 occupies one slot in the Model 3000 3RU rack chassis, which can house one or two power
supplies, one Model 3020, and up to six hot-swappable transmitter or receiver modules. A DB-25 connector on
the rear of the chassis may be used for fault monitoring. (See IOM3000C for complete details.) The following
conditions will trigger a summary fault on the chassis DB-25 connector: System Under Temp, System Over
Temp, RF Input Low on the primary path.
3RU Power Supply Description
Four power supply modules may be specified. The Model 3000UC-NN power supply provides universal AC
power to the units installed in the chassis. The Model 3000UB-NN supplies universal AC power and adds
SNMP or web-based system monitoring capability. Model 3000UE-NN provides -48 Volts DC, and the Model
3000UD-NN is the SNMP version, also providing -48 Volts DC. Regardless of the model ordered, one or two
power supplies may be accommodated in the 3RU chassis. The power supplies feature a green “Power On”
LED that indicates when the chassis is receiving power. A ground point on the front panel provides a common
ground for all modules installed in the chassis. The power supplies meet UL requirements. See IOM3000C for

Inspection
Remove the units from their shipping container. Any in-shipment damage that may have occurred should be
visually apparent. Look for bent or damaged connectors or mounting brackets. Claims for damage incurred in
shipment should be made directly to the transportation company in accordance with their instructions. Save
the shipping cartons until installation and performance verification are completed.
General Module Installation
The modules come pre-installed in the 3000 chassis. Make sure that adequate space is available for cabling and
safe access for inspection or troubleshooting. When replacing modules, align the top and bottom of the module with the module guides in the 3RU rack. Push the module firmly to engage the rear power plane connector.
NOTE
When using redundant power supplies, apply power to the power supply before installation into the rack chassis. If
power is not at the power supply at installation, an alarm condition will be reported to the DB-25 connector located at
the rear of the rack chassis. See IOM3000C for a list of faults that may be reported.

Safety Precautions
The optical emission from the units are laser-based. Class IIIb, and may present eye hazards if improperly
used. NEVER USE ANY KIND OF OPTICAL INSTRUMENT TO VIEW THE OPTICAL OUTPUT OF
THE UNIT. Complete laser safety procedures may be downloaded at http://www.forceinc.com/techbull/lasersafety-procedures.pdf. As always, be careful when working with optical fibers. Fibers can cause painful injury if
they penetrate the skin.
Operation Overview
The Model 3020 is a relatively simple product designed to allow a fully redundant, and thus highly reliable
fiber optic L-Band or IF link to be created.
Figure 3 Model 3020 RF Switch Block Diagram
The 3020 operates as follows: First a portion of the primary and secondary RF inputs are split off and fed to
wideband RF detectors. The output of the Primary Wideband RF Detector is fed to the DSP and the PRIMARY RF LEVEL test point on the front panel. The output of the Secondary Wideband RF Detector is fed
only to the DSP. The DSP considers the input from the Wideband RF Detector(s) along with the current state
of the unit and the settings of the various buttons and switches and decides whether the Solid State RF Switch
should be configured to output the primary or secondary RF input. The DSP illuminates the various status
LEDs to convey the current unit configuration. The DSP sets the analog PRIMARY TRIP POINT via a digital-to-analog converter (DAC).

RF Level Primary Trip Point
In order to properly utilize the 3020 it is important to understand how the RF input levels relate to the DC
voltages that can be measured on the PRIMARY RF LEVEL and PRIMARY TRIP POINT on the front
panel of the 3020. In order to measure these voltages, connect the ground lead of a digital voltometer (DVM)
to the ground terminal on the power supply. Connect the positive lead of the DVM to one of the two test
points on the 3020. Figure 4 shows the curve of the average RF input response that can be used to convert
from RF Level in dBm to Voltage and vice versa. This figure applies to the PRIMARY RF LEVEL and PRIMARY TRIP POINT. This plot was generated using a single tone at 1500 MHz. The voltage response will vary
somewhat across frequency.
Figure 4 Test Point Voltage vs. RF Input Level
The operation of the 3020 is very straightforward. Use the curve in Figure 4 to determine the trip point threshold. For instance if the desired RF trip point is -20 dBm, then the PRIMARY TRIP POINT voltage should be
set to approximately 900 mV using the UP and DOWN buttons. This voltage can be adjusted from 0 mV to
about 2,450 mV in 80 mV steps.
IOM3020 Revision 5.0
9
Model 3020 RF Switch Module
User Manual
The UP and DOWN buttons may also be held down to change the voltage more quickly. If the UP button is
held down, the PRIMARY TRIP POINT voltage will increase about 100 mV per second. If the DOWN button
is held down, the PRIMARY TRIP POINT voltage will decrease about 100 mV per second.
NOTE
The PRIMARY TRIP POINT voltage is updated to non-volatile memory after no buttons have been pushed on the front
panel for 10 seconds. Once non-volatile memory has been updated the PRIMARY TRIP POINT voltage will be held even
if the unit is power cycled.
Modes of Operation
There are three operating modes, Secondary, Auto, and Primary. In the Secondary mode, the 3020 is forced to
connect the secondary RF input channel to the RF Output. In the Primary mode, the 3020 is forced to connect
the primary RF input channel to the RF Output. In the Auto mode, the 3020 will connect the primary RF
input channel to the RF Output as long as the PRIMARY RF LEVEL is greater than the PRIMARY TRIP
POINT. If the PRIMARY RF LEVEL drops below the PRIMARY TRIP POINT, even for an instant, the 3020
will connect the secondary RF input to the RF Output. This connection will remain until the PRIMARY RF
LEVEL is once again greater than the PRIMARY TRIP POINT at which time the 3020 will connect the output to the primary RF input. Figure 5 presents the same information about the operating modes in a State Diagram Format.

Cleaning
If the units need to be cleaned, avoid the user of all solvents and use low-pressure clean air to remove loose
dirt. Use low-pressure clean air to clear the connectors of any debris. Dirty or scratched connector end faces
will greatly reduce the units performance. Foam-tipped swabs such as the 2.5mm Mini Foam Swab offered by
Fiber Instrument Sales (P/N F1-0005) may be saturated with denatured alcohol* and inserted into the optical
port for cleaning. DO NOT INSERT A DRY SWAB INTO THE OPTICAL PORT AS THIS MAY DAMAGE THE FIBER END FACE. Many fiber optic installations experience degraded performance due to dirty
optical connector end faces. For complete connector cleaning instructions, download http://www.forceinc.com/
techbull/optical-connector-cleaning.pdf from Force’s web site.
Troubleshooting
Common problems include lack of power, reversed power (stand-alone units only), or improper input levels.
The units are designed to work with a 75 Ohm system or a 50 Ohm system depending on the model ordered. A
number of indicator LEDs on the units may assist in troubleshooting. These allow the user to quickly assess the
nature of any major unit malfunctions.

Shipping and Handling Precautions
The units are, in general, very rugged and can withstand the stresses of most shipping and handling circumstances. However, the following precautions should be taken:
1) When the units are shipped they should be wrapped in a protective material, such as bubble wrap, to protect against excessive jarring and to prevent damage to the external finish of the units. Always use packing
material to separate multiple units that are packaged together.
2) Care should be taken not to drop or strike the units in any way, especially around the optical connectors.
3) The units should never be submersed in any liquid. SEVERE SHOCK HAZARD!
Storing the Unit
If a unit is to be out of use for an extended period of time, the following steps should be taken to ensure the
preservation of the unit:
1) The storage temperature range is -40°C to +60°C. Allow time for unit to restore to room temperature
(and dry out) before power is applied.
2) A low humidity environment is preferable for long term storage.
3) All connectors should be covered with active device receptacle caps.
